DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention are provided for illustration purpose only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

An exemplary apparatus and a method for providing an emotion expression service in a mobile communication terminal will be described. Herein, the emotion expression service denotes a service for expressing the emotion of a user of a calling terminal (i.e. a calling party, hereinafter a user of a calling terminal is referred to as “a calling party”) using a video call service.

In an exemplary embodiment, the mobile communication terminal using a video call service recognizes shaking of the calling terminal or an expression on a display unit and provides an emotion expression event for expressing the emotion of the calling party. Herein, the emotion expression event may include vibration of the mobile communication terminal, a sound effect generated by the mobile communication terminal, and a screen effect generated by the mobile communication terminal.

In an exemplary embodiment, the mobile communication terminal performs a method for recognizing shaking by the user of the calling terminal or an expression on a display unit and provides an emotion expression service as illustrated in FIG. 1.

FIG. 1 is a flowchart illustrating a procedure for providing an emotion expression service in a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the mobile communication terminal performs a video call with the calling terminal in step 101.

In step 103, the mobile communication terminal determines whether the emotion expression service is set by a user.

If it is determined that the emotion expression service is not set, the mobile communication terminal ends the process according to the present invention. Here, the mobile communication terminal provides a general video call service.

On the other hand, if it is determined that the emotion expression service is set, the mobile communication terminal determines whether shaking of an image on a video call screen is detected in step 105. For example, the mobile communication terminal determines whether the differences among frames, i.e., differences among pixel values of frames that configure the video call screen, is greater than a reference value. Here, the mobile communication terminal may determine an average of differences among frames within a time interval and determine whether the image on the video call screen shakes.

When the average of differences among frames is less than the reference value, the mobile communication terminal determines that the image on the video call screen is not shaking. Therefore, in the 109, the mobile communication terminal determines whether information of emotion expression is detected in images of the video call screen. For example, the mobile communication terminal may recognize a facial expression of a calling party in received images from the calling terminal and determine whether the information of emotion expression corresponds to an emotion such as a smile expression, an angry expression and the like.

Otherwise, if it is determined in step 105 that the average of differences among frames is greater than or equal to the reference value, the mobile communication terminal determines that the image on the video call screen is shaking. Therefore, in step 107, the mobile communication terminal generates an event corresponding to the shaking image. For example, the mobile communication terminal generates a vibration. In an exemplary implementation, the mobile communication terminal determines a vibration strength corresponding to the amount, duration or strength of the shaking and generates a corresponding vibration. The amount, duration or strength of the shaking is determined by the differences among frames.

In step 109, the mobile communication terminal determines whether information of emotion expression is detected in images of the video call screen. For example, the mobile communication terminal may recognize a facial expression of the calling party in the video call screen and determine whether the information of emotion expression corresponds to a recognized expression such as a smile expression, an angry expression, and the like.

If it is determined that information of emotion expression is not detected, the mobile communication terminal determines whether the video call terminates in step 113.

Otherwise, if it is determined that information of emotion expression is detected in step 109, in step 111, the mobile communication terminal generates an emotion expression event corresponding to the information of emotion expression detected in step 109. For example, if the smile expression of the calling party is detected, the mobile communication terminal may generate the sound of laughter. As another example, if the smile expression of the calling party is detected, the mobile communication terminal may display a screen effect such as a smile expression or generate a vibration.

Then, the mobile communication terminal determines whether the video call terminates in step 113.

If it is determined that the video call is not terminated, the mobile communication terminal returns to step 105 and performs the described processes.

Otherwise, if it is determined that the video call is terminated, the mobile communication terminal ends the process according to the present invention.

As described in the above exemplary embodiments, the mobile communication terminal generates an emotion expression event, when the information of shaking or emotion expression is detected in images on the display unit.

In another exemplary embodiment, the mobile communication terminal generates an emotion expression event corresponding to the received information of emotion expression from the calling terminal.

FIG. 2 is a flowchart illustrating a procedure for providing information of emotion expression to a called terminal in a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the mobile communication terminal performs a video call with a called terminal in step 201.

In step 203, the mobile communication terminal determines whether the emotion expression service is set by a user.

If it is determined that the emotion expression service is not set, the mobile communication terminal ends the process according to the present invention. Here, the mobile communication terminal provides a general video call service.

On the other hand, if it is determined in step 203 that the emotion expression service is set, the mobile communication terminal determines whether shaking of the mobile communication terminal is detected in step 205. For example, the mobile communication terminal may detect shaking of the mobile communication terminal using a Geo Magnetic Sensor. As another example, the mobile communication terminal determines whether a vibration generation button is input by the user.

If it is determined that shaking of mobile communication is not detected in step 205, the mobile communication terminal determines whether the video call terminates in step 209.

Otherwise, if it is determined that shaking of mobile communication is detected in step 205, the mobile communication terminal transmits an event request signal to the called terminal using the video call service in step 207. For example, the mobile communication terminal adds the event request information to the video call signal and transmits the video call signal to the called terminal. As another example, the mobile communication terminal may transmit the event request information using an extra control signal. Herein, the mobile communication terminal transmits the event request information using a control signal according to the H.324 protocol to the called terminal. Also, the mobile communication terminal may transmit the event request information through a control signal using an Internet Protocol (IP) of a Packet Switched Network.

After that, the mobile communication terminal determines whether the video call terminates in step 209.

If it is determined that the video call is not terminated, the mobile communication terminal returns to step 205 and performs the described processes.

Otherwise, if it is determined that the video call is terminated, the mobile communication terminal ends the process according to the present invention.

As described in the above exemplary embodiments, when the shaking of the mobile communication terminal is detected, the mobile communication terminal transmits the event request information.

In another exemplary embodiment, when information of emotion expression is detected in images for transmission to the called terminal, the mobile communication terminal transmits the event request signal corresponding to the information of emotion expression to the called terminal. For example, the mobile communication terminal may include a camera module for capturing images of the user to be transmitted to the called terminal. If information of emotion expression is detected in images captured by the camera module and to be transmitted to the called terminal, the mobile communication terminal may transmit an event request signal corresponding to the detected information of emotion expression.

As described above, if the mobile communication terminal transmits the event request signal to the called terminal, the called terminal generates the emotion expression event corresponding to the event request signal as illustrated in FIG. 3.

FIG. 3 is a flowchart illustrating a procedure for providing an emotion expression service in a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the mobile communication terminal performs a video call with a calling terminal in step 301.

In step 303, the mobile communication terminal determines whether the emotion expression service is set by a user.

If it is determined that the emotion expression service is not set, the mobile communication terminal ends the process according to the present invention. Here, the mobile communication terminal provides a general video call service.

Otherwise, if it is determined in step 303 that the emotion expression service is set, the mobile communication terminal determines whether the event request signal is received from the calling terminal using a video call service in step 305.

If it is determined in step 305 that the event request signal is not received, the mobile communication terminal determines whether information of emotion expression is detected in images of a video call screen in step 309. For example, the mobile communication terminal may recognize a facial expression of a calling party in the video call screen and determine whether the information of emotion expression corresponds to an emotion such as a smile expression, an angry expression, and the like.

Otherwise, if it is determined in step 305 that the event request signal is received, the mobile communication terminal generates a shaking event in step 307 corresponding to the event request signal. For example, the mobile communication terminal generates a vibration. In an exemplary implementation, the mobile communication terminal determines a vibration strength corresponding to the amount, duration or strength of the event request signal and generates a corresponding vibration.

Then, the mobile communication terminal determines whether information of emotion expression is detected in images of the video call screen in step 309. For example, the mobile communication terminal may recognize a facial expression of the calling party in the video call screen and determine whether the information of emotion expression corresponds to an emotion such as a smile expression, an angry expression, and the like.

If it is determined that information of emotion expression is not detected in step 309, the mobile communication terminal determines whether the video call terminates in step 313.

Otherwise, if it is determined that information of emotion expression is detected in step 309, the mobile communication terminal generates an emotion expression event in step 311 corresponding to the information of emotion expression detected in step 309. For example, if the smile expression of the calling party is detected, the mobile communication terminal may generate the sound of laughter. As another example, if the smile expression of the calling party is detected, the mobile communication terminal may display a screen effect such as a smile expression or generate a vibration.

Then, the mobile communication terminal determines whether the video call terminates in step 313.

If it is determined that the video call is not terminated, the mobile communication terminal returns to step 305 and performs the described processes.

Otherwise, if it is determined that the video call is terminated, the mobile communication terminal ends the process according to the present invention.

In other words, an exemplary method for providing an emotion expression service in a mobile communication terminal comprises identifying, by the mobile communication terminal, information of emotion expression in received images from a calling terminal using a video call service, and generating, by the mobile communication terminal, an event corresponding to the identified information of emotion expression.

Further, the information of emotion expression may comprise at least one of a shaking of the received images and a visible expression of a calling party.

In another exemplary embodiment, the mobile communication terminal generates an emotion expression event corresponding to the received event request signal from the called terminal.

An exemplary block diagram of a mobile communication terminal for providing an emotion expression service is described below.

Referring to FIG. 4, the mobile communication terminal may include a control unit 400, a camera unit 402, a display unit 404, an input unit 406, a memory 408, a communication module 410, a voice processor 412, a microphone 414, a speaker 416, and a vibrator 418.

The control unit 400 performs processing and control for general operation of the mobile communication terminal. For example, the control unit 400 performs processing and control for voice telephony and data communication. According to an exemplary embodiment of the present invention, the control unit 400 controls the providing of an emotion expression service during a video call. For example, the control unit 400 controls the generating of an emotion expression event when the shaking of an image from a calling terminal is detected or the information of emotion expression is included in the image of the calling terminal as detected on the display unit 404, as illustrated in FIG. 1. As another example, the control unit 400 controls the generating of an emotion expression event corresponding to a received event request signal from a calling terminal as illustrated in FIG. 3. In this state, the control unit 400 controls the transmitting of an event request signal to the called terminal, when at least one of information of emotion expression is detected in images for transmission to the called terminal and shaking of the images for transmission to the called terminal as illustrated in FIG. 2.

The camera unit 402 photographs an image, and converts the photographed image to corresponding digital data. The camera unit 402 processes the digital data and obtains a still image, then outputs the still image to the control unit 400 or display unit 404.

The display unit 404 displays state information generated during operation of the mobile communication terminal, characters input by a user, moving images and still images. Also, the display unit 404 displays moving images and still images input from the camera unit 402.
